Enormously large tits.
A more thought-provoking and graphic description of big 'ol titties. Phrase describing the size and shape of the teat more so than the breast itself.
it's kind of a "special" code. that way, you can tell the fellas (or ladies) that another women has some huge ass titties with them nearby. that way they (hopefully) won't know what you are talking about. ...that is.. until it's to late.
"damn, you see that chick. she has some tig ol bitties" ...and the fellas agree by sayin.."yep. tig ol bitties"
